Do you have tested the dlopen/dlsym stuff of this libtool ? I' ve got the
following errors compiling libltdl and mdemo:

----- without auto-import binutils --------------------

$ ./mdemo foo1.la

I have debugged, but currently I can't find the reason. I have to study more the
internals.
Perhaps you have an idea ?
